Reduction Division
Meiosis II is also called __?__.
Equational Division
In terms of human cells that enter meiosis I: how many chromosomesdo these cells have?
46
In terms of human cells that enter meiosis I: are the chromosomesof these cells duplicatedor unduplicated?
Duplicated
In terms of human cells that have completed meiosis I (but have not yet entered meiosis II): how many chromosomes do these cells have?
23
In terms of human cells that have completed meiosis I (but have not yet entered meiosis II): are the chromosomes of these cells duplicatedor unduplicated?
Duplicated
In terms of human cells that have completed meiosis II: how many chromosomes do these cells have?
23
In terms of human cells that have completed meiosis II: are the chromosomesof these cells duplicated orunduplicated?
Unduplicated
What is the short phase between meiosis I and meiosis II called?
Interkenesis
Are cells that enter meiosis I diploid or haploid?
Diploid
Are cells that enter meiosis II diploid or haploid?
Haploid
Are cells that complete meiosis II diploid or haploid?
Haploid
What happens during interphase before meiosis I?
DNA replication
What word means "pairing of homologous chromosomes"?
Synapsis
What are homologous chromosomes?
Same genes carried on each chromosome (ex: eye color).
Why does crossing overoccur?
So there can be an exchange of genetic material leading to genetic diversity (variation).
How many chromosomes does a human lymphocytehave?
46
How many chromosomes does a human gamete have?
23
In what phase of meiosisdoes crossing overoccur? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
Prophase I
In what phase of meiosisdoes pairing of homologous chromosomes occur? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
Prophase I
In what phase of meiosisdo sister chromatids split and are pulled toward opposite poles of the cell? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
Anaphase II
In what phase of meiosisdoes the cell invaginates to form 2 haploid cells with duplicated chromosomes? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
Telophase (and Cytokenesis) I
In what phase of meiosisdoes the cell invaginates to form 2 haploid cells with unduplicated chromosomes? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
Telophase (and Cytokenesis) II
In what phase of meiosisdo homologous chromosomes line up in pairs along the center of the spindle? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
Metaphase I
In what phase of meiosisdoes a haploid number of chromosomes first becomes visible? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
Telophase I
In what phase of meiosis does the spindle form in a cell with a diploid number of chromosomes? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
